We're still going to keep our focus on polynomials for the moment, but now we want to describe those polynomials using limit notation. Using limits to describe the behavior of a polynomial near a constant is never very interesting because for all polynomials and all real numbers , it is always the case that .

First, describe in words what it means to say that .

What property do polynomials possess that makes it safe to say that for all polynomials ?

What is ?

If is a polynomial, which of the following is equal to ?

We can also use limit notation--specifically, limits at infinity--to describe a function's end behavior. Enter a polynomial function such that and .

If is a polynomial and , what can you say about ?
